Find the value of x. Round the length to the nearest tenth. The diagram is not drawn to scale.
1 answer:
For the given triangle, the value of x is 2,880.2 m.
Step-by-step explanation:
Step 1:
The sum of the angles on a straight line is 90°. It is given that the sum of the upper sides angle and 10° is 90°.
So the triangle has an angle of 80° on the top side.
Step 2:
For the top side, the hypotenuse measures x m and the adjacent side measures 500 m.
To determine the value of x, we determine the cos of the given angle.
So rounding this off, we get the value of x is 2,880.2 m.

Answer:
15% markdown
Step-by-step explanation:
In order to find the markdown, take the lowered price and place it in a fraction as the numerator, and the initial price as the denominator. This looks like:
with this fraction, we're going to multiply it by 100, with an equation looking like this,
×
once we multiply(typically using a calculator, though manually is possible of course) we get 85.
In order to find the markdown price however, we need to subtract 85 from 100, getting 15. This is the markdown price, because it's the percentage of the initial whole that the price went down by. Can check by finding 15% of 975, which is 828.75
